Bilberry Wood was planted in the mid-Victorian period, at about the same time as Nethergill was built as a lodge.

Heather

Heather

Heather, also known as ling, Calluna vulgaris, grows in the drier parts of the wood, including on tussocks raised about the boggy areas and, here, from a crevice on a fallen pine trunk. Heather is an indicator of dry acid soils. The abundant heather and bilberry here are a sign that the wood has been only lightly or moderately grazed.

Lightly-grazed pinewood with tall heather is classified as National Vegetation Classification community W18.

White Shorthorn

White Shorthorn bull

As happens to me with so many farm animals, as soon as I tried to photograph him in a relaxed, natural pose, this White Shorthorn bull immediately stopped what he was doing – grazing – and looked straight at the camera with a suspicious ‘what are you doing?’ expression.

White Shorthorns are a rare breed, well adapted to being out in all weathers and here at Nethergill Farm in Langstrothdale they’re free to roam, either in the fields around the farm or on the open hillside beyond Oughtershaw Beck. They tend to have a daily routine, making their way down from their preferred overnight quarters towards the beck during the morning.

White Shorthorn Bull

Along with some light grazing by a limited number of sheep, the White Shorthorns act as landscape managers here, rather like the Longhorns on the Knepp Wildland Project in West Sussex.

Wildlife projects at Nethergill include managing the meadows to encourage wild flowers, the woodland to encourage red squirrels and the beck for fish, insects, birds and the occasional visit by an otter.

Trump

Chris & Fiona Clark run the award-winning Eco-Farm at Nethergill but the bull belongs to a farmer friend of theirs in Cumbria – Gordon
“Gordon takes our calves when old enough,” Fiona tells me, “and we use his mature bulls to cosy up with our girls. 
‘Trump’ is the new kid on the block, 2 years old. Probably weighs 700kg approx. 
The ladies rule at Nethergill he sidles up to each female over several weeks. 
His technique obviously worked as all bar 1 are in calf due this Summer.”

Ravens

moorRagged wisps of grey cloud trail down from the edge of the moor.

ravenRavens make their way across the hillside. With primaries outspread like spiky fingers, one of them quarters the open ground then plunges down amongst the grasses and rushes.

Ravens mate for life and often stay together as a pair throughout the year so, as Bertel Bruun suggests in the Hamlyn bird guide: “two dots moving along a ridges are often Ravens.”

We get a chance to compare them when a small group of carrion crows fly up the valley and settle in a tree. They seem altogether more lightweight with a less powerful way of flying. Barbara’s instant reaction when the raven appeared over the ridge was that it was a buzzard (although she’s still not convinced that we really did see a pair of ravens, and not a pair of crows!).

crowflyRooks and jackdaws which are congregating on the rough pasture below Nethergill Farm along with a flock of starlings, are generally more sociable than either carrion crows or ravens. I’d describe crows as cawing more raucously and harshly than rooks.

The pair of ravens fly over the valley and we briefly hear them vocalizing. To us it sounds like a rather nasal grunt but Bruun characterizes the call as a deep, resonant ‘pruuk’. They also have a ‘krra-krra-krra’ alarm call and, in the spring, a range of clucking noises.

We need to see ravens more often to get familiar with the character of the bird.

Kestrels

kestrelsKestrels are doing well in this stretch of Langstrothdale. We’ve seen them almost every time that we’ve been out. This morning two fly down the slope, the first with some scrap in its talons. The second dives down on it as they fly over the stream but the first retains its prize and settles in a tree.

Greenfield Valley

9 a.m.: The mist has cleared and we can see the conifer plantations of the Greenfield Valley again.

Fieldfares and starlings
Fieldfares and starlings

Two fieldfares settle on the rushy pasture in front of the farm. With their grey rump, greyish head and slithers of white on the front of their folded wings they’re more strikingly smart than the resident mistle thrush and the female blackbird which are also about this morning.

When one of them perches on the power line and starts preening, we see the dark band at the end of its tail and two tear-shaped streaks of chestnut on its breast.

Post Pecker

great-spotted woodpeckerA male great spotted woodpecker probes every crevice on the stout timber corner post of a wire fence. Having checked all around it, it perches on top then flies to the adjacent fence post. The slimmer post evidently doesn’t offer the same possibilities so it flies off, with bouncing flight, to the power line post and continues probing.

Two dippers are working their way down the beck towards Oughtershaw this morning; one wades in then completely submerges.

heronOn an afternoon walk to the Greenfield Valley we see a heron flying up Langstrothdale along Oughtershaw Beck, four pipits (no doubt meadow pipits) and a kestrel.

Zaphrentis

ZephrentisPausing to take a closer look at some crushed limestone on a forestry track, I find this complete fossil of a funnel-shaped coral amongst the more common macaroni-like lithostrotion corals and the stout toadstool cap-shaped shells of brachiopods (which I’m assuming are Productus).

The funnel-shaped coral is Zaphrentis phrygia, (not Zephrentis, as I’d previously misspelled it on this page) given its species name because of its resemblance to the Phrygian cap, a tall, pointed felt cap which was worn with the point tilting forwards.

Harebell, yarrow and herb robert are still in flower on the banking below the drystone wall on the road immediately to the south of Oughtershaw.

Mist in the Dale

seeds heads of grassNethergill Farm, Langstrothdale, 9.10 a.m.: The trees on the far side of Oughtershaw Beck have faded away as the morning mist fills the valley. I was keen to study clouds during our stay here, now we’re in one.

StarlingBarbara counts thirty-eight starlings which have cascaded out of the mist and settled along the power line; there are at least twice as many below – so a flock of more than a hundred in total – but as they are performing a Mexican wave of short leap-frogging flights to get to the leading edge of their feeding party on the rushy sheep-nibbled turf, it’s impossible to count them.

crowAttracted to the shrubs and the bird feeders in front of the farmhouse are a couple of blue tits, a robin and a blackbird. Five carrion crows perch on the cables of the power line pole nearby.

The Track to Swarthgill

Hammock web
Hammock web

10.40 a.m.: The mist has closed in as we walk up Langstrothdale along the track to Swarthgill Farm, so we can’t see beyond the power lines a couple of hundred yards away down the slope. Droplets sparkle on the seed heads of grasses and on hammock-webs, slung a few inches from the ground amongst the stiff leaves of sedges.

wrenA pair of wrens are checking out the crevices in the lichen-splashed drystone wall, pausing between sorties to meet up again, bobbing and perking up their tails as they face each other, perching on adjacent capstones.

pipitfltA meadow pipit emerges from the mist in bouncing flight, twenty feet above the moor, calling as it goes: “Pi-pit! Pi-pit! Pi-pit!”

We hear but don’t see a red grouse calling “G-bak! G-Bak! G-bak!” from somewhere down near the beck.

cock pheasantMore startling is the cock pheasant that explodes with indignant grockling in wall-top height flight as we reach the tree-lined drive to Swarthgill. Its rhythm is like a bicycle with badly damaged spokes careering along, alarmingly out of control as it passes us by:

“GerrROK! GerrROK! Gerr ROK!”

Reed Bunting

reed buntingA small group of reed bunting fly to the tops of the small trees in the shrubbery around the garden of the farmhouse. There’s a male in winter plumage – brown cap, black bib – with at least two brown streaky companions: juveniles or females.

The reed bunting feeding technique this morning is to gently hop up a twig, carefully inspecting both sides of it and picking off food items (probably insects, spiders and any other invertebrate that they come across).

On this still, humid morning, a little cloud of mosquito-sized insects, probably winter gnats, hovers above us just after we’ve passed the shelter belt of trees growing alongside one of the gills (streams in a sometimes deep channel on the hillside) which give Nethergill its name: the farm sits between two gills.

Dipper

Oughtershaw Beck2.30 p.m.: We get a good view of a dipper as it sits for a few minutes on the end of a mossy rock in Oughtershaw beck. It’s motionless except for its nictitating membrane: an inner eyelid, which keeps flashing white as it moves across the eye. To me this ‘third eyelid’ appears to pass over the eye from bottom to top but I believe it actually crosses from back to front. Diving birds use their transparent nictitating membrane underwater. The dipper’s eyelid appears to be white but I suspect that it is transparent or semi-transparent from the point of view of the dipper.

dipperI didn’t catch the bird in my  photograph of the beck (above), but tried to memorise the shapes and colours by watching it with binoculars for as long as possible and drawing it from memory later (left).

There are no grey wagtails or sandpipers, which we frequently saw along the beck during our visit here in June.

Goosander Fishing

Oughtershaw Beckgoosander3 p.m.: A red-headed goosander (a female or a first year bird) waddles up through the rippling shallows of the wide, rocky stretch of the beck where the Nethergill sheep find their way across.

It dives as it continues into deeper water above the riffles then on a narrower, deeper bend, it dives midstream, emerging by the steep, undercut bank on the outside bank of the meander.

goosanderThere’s a lot of splashing – as if it’s bathing – but it wouldn’t be doing that under an overhanging bank. Is it driving small fish under?

It thoroughly investigates under the bank, swimming around right under the overhang. The only prey that I briefly catch a glimpse of in its bill is broad and brownish, perhaps a bullhead.

At the top end of this stretch, where the beck broadens out a little, it goes through a bathing routine, this time in the middle of the stream.

Lenticular Clouds

Ingleborough sunsetLate afternoon and I pull in at the viewpoint to photograph the cloudscape as we cross the moor top between Hawes and Langstrothdale.

Lenticular cloud

“I think those clouds are caused by air rising as it moves over a hill,” I suggest to the man who has pulled in just behind us to photograph them on his iPad, “I’ve been reading The Cloudspotter’s Guide, but I can’t remember what they’re called.”

“Lenticular clouds?”

“That’s right; you are a cloud spotter?”

“No . . . just nutty!”

Just as I’ve got myself back in the car and out of the cool breeze, I notice another cloud-spotting feature to the left of the lenticular cloud that is hanging above Ingleborough and I grab my camera.

Sun Dog

“Have you seen the sun-dog?” I ask the man with the iPad; “They’re caused by ice crystals in high clouds refracting the light and they always appear at a certain distance from the sun – I think it’s something like 23 degrees.”

“I wonder if that’s because we’re at 53 degrees north?” He surmises.

I wasn’t too far out, it’s 22° but the phenomenon is a halo effect caused by tiny ice crystals in translucent cloud, so the effect is independent of latitude.

Sunset over Langstrothdale

With 'sunset' setting.

Half an hour later I take the opportunity to photograph sunset over the top end of the dale from the first floor window of our barn conversion accommodation at Nethergill Farm.

sunset langstrothdale

It’s the first time that I’ve tried the ‘sunset’ setting on my camera. It might have warmed up the colours a little but it’s more successful than the camera’s default setting which attempts to adjust the exposure to make the scene resemble regular daylight.

Langstrothdale

Nethergill Farm, Langstrothdale
Nethergill Farm, Langstrothdale, yesterday morning as the sun failed to clear the low cloud.

Nethergill Farm, 1.10 p.m.: Cumulus clouds are towering over Langstrothdale and the thunderstorms that the forecast suggested were a possibility would now be welcome as even here in the shade of the old barn the temperature is climbing into the high seventies Fahrenheit, 25 C.

A cuckoo is calling on the far side of the valley. Meadow pipits are the birds we see most often on the road across the moor to Hawes, so it will have plenty of nesting pairs in its territory.

The farm’s resident blackbird sings from the ash tree, which is covered in sprays of blossom, which is now going over, and freshly sprouted bright green fronds of leaves.

Goldfinches chatter excitedly in its canopy. A gentle breeze sighs as it passes across the valley ahead of the gathering cloud but does nothing to freshen the atmosphere.

A pheasant explodes in a brief grockle of indignation, flies murmur, a cockerel crows: a strangulated wail. The hens here at Nethergill farm ‘are still learning’ so Fiona added an extra egg to the small but deep yellow yoked half dozen that she gave us in our welcome pack for our self-catering apartment, the Hay Mew. Also included, slices of her homemade flapjack which has been enticing Dales Way walkers to take a break here for the last five years.

Swarthghyll

buzzard2.45 p.m., Bilberry Wood, Langstrothdale: We could hear a buzzard mewing but couldn’t spot one circling or perching in the pines on the far side of the beck; it was on the moorland edge on the slope beyond, perching on a fence-post. It was still there and still calling when we walked back, half an hour later.

starling3 p.m.: Starlings nest beneath the roof tiles at Swarthghyll Farm, Langstrothdale. House martin and swallow fly in at the barn window below.

green-veined white3.20 p.m.: A green-veined white is sunning itself on a bank by the track across the moor, after a brief chase with a rival. It has fine dark veins on its upper wings but lacks the spots and borders that you see on many white butterflies (including most green-veined whites). A brief glimpse of the veins of its underwing helps confirm that it really is a green-veined.

pied wagtail5 p.m. riverside hide, Nethergill Farm: A pied wagtail feeds amongst the rocks on the beck, which is running low. It flies vertically to snap an insect in mid-air, then switches its attention to the beck-side pasture, darting to pick up insects from the clumps of rushes.

Gryke

grykeThis gryke gives shelter to the kind of plants that you’d see in a hedgerow or in woodland. A velvety coat of moss on the limestone indicates how far the humid, sheltered zone of the gryke extends. In this particular crevice I noted wild garlic, dogs mercury, meadowsweet and creeping thistle.

A gryke is a crack between the clints (slabs) that make up a limestone pavement.

It might be sheltered for the plants down there but there was a cool breeze blowing down the valley this morning and the slab of limestone that I was sitting on proved surprisingly uncomfortable, even though I was sitting on a thin foam mat, so this is as far as I got with my sketch.
